A Frost Protection Design for Fruit Trees in Southwest Colorado
The project explores the feasibility of producing commercial quantities of fruit in the high and arid environment of Southwestern Colorado by using low-volume water delivery systems for...
Chaos Characteristics of Tree-Ring Series
Thirteen tree-ring series from the Salt and Verde River basins in Arizona are studied to distinguish between chaos and randomness. A chaotic moving average model that represents the time...
Nitrogen Leaching from Young Florida Citrus
Sixteen buried drainage lysimeters were constructed from 2300 L polyethylene containment basins for the study. The lysimeters were 2.1 m in diameter by 0.8 m deep and were filled with...
Relation of Channel Stability to Scour at Highway Bridges Over Waterways in Maryland
Data from assessments of channel stability and observed-scour conditions at 876 highway bridges over Maryland waterways were entered into a database. Relations were found to exist among...
Use of Event Trees and Economic Models In Evaluating Hydroelectric Rehabilitation Projects
Evaluation of Palmiter Erosion Remediation Techniques ? A Case Study
Quantifying Uncertainty in Site Characterization
The uncertainties in determining the true geologic conditions at the proposed high-level nuclear waste repository at Yucca Mountain, Nevada needed to be determined as part of the Exploratory...
Water Quality Effects on Eucalyptus ET
The researchers are testing established methods for measuring evapotranspiration (ET) from a 6-year old plantation of Eucalyptus camaldulensis containing about 3,000 trees per ha in a...
On-Off Terminal Ship-to-Rail Transfer
The intermodal situation of U.S. ports is still evolving, and port planners will be facing difficult decisions regarding IM Configurations. This article was intended to assist 'perplexed'...
Scenario Evolution: Interaction Between Event Tree Construction and Numerical Analyses
Construction of well-posed scenarios for the range of conditions possible at any proposed repository site is a critical first step to assessing total system performance. Event tree construction...
Heuristic Optimization of Water Distribution Systems
A design heuristic for the optimization of water distribution systems is presented. Algorithm TREESEARCH finds a near optimal core tree layout. Algorithm REDUNDANCY adds redundant links...
Hugo - Lessons Learned
This paper is based on ground surveys along the South Carolina coast from Edisto Island north to Myrtle Beach. It also includes ground surveys as far inland as Charlotte, North Carolina....
Transpiration by Douglas Fir Using Lysimeters
During the spring of 1971 a 28 m Douglas fir tree was installed in a weighing lysimeter. Some details of construction are presented. The weighing mechanism consisted of eleven lengths...
Drainage Lysimeters for High Water Table Citrus Studies
Forty drainage lysimeters were installed in 1988 to conduct water quality and consumptive use studies for citrus. The lysimeters were designed to simulate the high water table conditions...
Landfill Park: From Eyesore to Asset
By reclaiming a 50 acre landfill as a recreational area, Cambridge, Mass. increased its open space by 20%. The park includes three softball and three soccer fields, one multisport field,...
Land Management and Water Yield in the Appalachians
Watershed treatments on the Fernow Experimental Forest have included individual tree selection, commercial clearcutting, clearcutting upper and lower halves of watersheds, clearcutting...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
Landslides and Cherry Trees -- Upgrading the Dalles Irrigation District
The Dalles Irrigation District recently began the process of applying for a federal loan to finance upgrading of the District's distribution system. The process included preparation...
Effect of Saline Irrigation Water on Tree Growth
A random block experiment using three types of soil, five different qualities of irrigation water, and three popular windbreak trees was conducted to measure the effects of soil type and...
Bank Erosion During the 1988-Flood in the Rumoi River
Observations of the bank erosion were performed in the Rumoi River after the flood in August, 1988. It was found from the detailed research that the pattern of the flood was an important...
